Hitachi Appliances will release the robot cleaner "minimaru" (RV-DX1) on November 19th.


In recent years, major domestic manufacturers have entered the robot cleaner market in a fierce battlefield, including "Rumba", which boasts overwhelming popularity in Japan. Minimal, which appeared with full satisfaction, is a fairly high-class line with a market price of around 100,000 yen. What kind of vacuum cleaner is it? I actually used it.

The bottom of the table is also shiny!

The biggest feature is a compact body with a width of 25 cm and a height of 9.2 cm. Even if you leave the chair on the dining table, it will carefully clean the area around your legs. In addition, you can't miss it even in low places such as sofas and beds, between furniture, and in corners of rooms that are usually difficult to clean. It weighs 2.3 kg and is easy to lift and move.



The main body is equipped with a uniquely developed driving control system "minimaru AI". It seems that it controls driving from more than 100 behavior patterns by quickly judging the surrounding situation with multiple sensors. The movement and direction change is very quick, giving the impression of being "quick". The sound is not so loud, and it is a hindrance to watching TV, but it is not a touch to my ears because I spend it normally.

I'll suck the trash!

The front "side brush" is very useful for cleaning. Since it protruded a little from the main body, it reached the corner of the room and the wall.




On the carpet, use a "scraping brush" to catch cotton dust without missing it.


When the battery is low or the home button is pressed, it will automatically return to the charging stand. After that, "dust press" that compresses dust and "automatic brush cleaning" that removes dust attached to the brush are automatically executed.



Driving in automatic mode is plenty of 1 hour. At the author's house, I tried to run through the living room, one room (Japanese-style room), and the corridor for a week's worth of garbage for minimalism, but I was surprised to see more garbage than I expected. I think that I was able to get rid of the trash as much as I did it under the sofa and between the furniture, which I always did properly.

The trick is to prepare in advance

It seems that the whole room is cleaned, but when I look at the automatic mode, I get the impression that the running is a little random. There are also elaborate modes and spot modes in the menu, so it's best to use them properly depending on the day.

The trick to cleaning evenly is not to do it all at once, but to use doors and furniture to separate it to some extent. Large furniture is fine, but it's smoother to keep your luggage off the floor. As with all robot vacuums in the first place, I think it's a good opportunity to clean up your house when you buy it.

I'm a little worried about driving when I'm away

I personally don't recommend driving when you're out, as it may come in contact with a small mat or a round flowerpot and stop. Is it efficient to do other household chores such as washing and cooking while running the minimalist? If there is something, it will notify you by voice, and you can remotely control it from the attached remote control, so you do not have to approach each other even if you are working in a remote place.



I have a weak waist and it is difficult to remove furniture when vacuuming, so it is convenient to have one small robot cleaner. However, if you have 100,000 yen, you will have a lot of options, so it is a good idea to choose a model that suits each household, such as "I want to clean while I'm not at home," "I have a lot of furniture," and "Emphasis on suction power." With the advent of compact minimalism, it seems that the entire lineup is on the market.
